This does mean you’re a little less likely to experiment with specs than you might be in Diablo 3. Instead, you earn one skill reset per difficulty (Normal, Nightmare, and Hell). Seasoned Diablo 2 players know this already, but those who started with Diablo 3 may be in for a rude awakening in Diablo 2 Resurrected, because you cannot freely respec your skills and abilities.
